Optical plankton: an optical oceanic probing scheme

Journal of Applied Remote Sensing, 2007
In this paper, we evaluate the possibility of a wireless sensor network concept operating in the oceanic environment. A population of underwater sensor nodes, termed "optical plankton," form a distributed sensor network characterized by the deployment of many miniature and low-cost sensors capable of profiling the particulate composition in the ...

The Analysis Of Ocean Optical Data

SPIE Proceedings, 1984
A new oceanographic instrument to measure underwater optical, biological and physical properties simultaneously has been built and used extensively at sea. The Bio-Optical Profiling System (BOPS) was designed for the rapid acquisition of data to accommodate shipboard 'synoptic' sampling strategies, often in conjunction with concurrent aircraft and ...

Optical properties of the ocean

Reports on Progress in Physics, 1973
Oceanic optical properties are reviewed. Topics covered include energy losses, refractive index effects, polarization, non- optical uses of optical measurements and measuring instruments. Throughout the article the optical difference between true oceanic and coastal water is emphasized.

Ocean Optics

1994
Since the publication of Jerlov's classic volume on optical oceanography in 1968, the ability to predict or model the submarine light field, given measurements of the inherent optical properties of the ocean, has improved to the point that model fields are very close to measured fields.

Optical studies in the Southern Ocean

Deep Sea Research Part II: Topical Studies in Oceanography, 2004
During the Austral summer of 1997-1998, measurements of absorption, attenuation, downwelling and upwelling irradiance were made in the Southern Ocean along a S-N transect at 6degreesE. Measurements were made to quantify the penetration of ultraviolet B radiation (UVBR) in the water column and daily doses of UVBR at different water depths, to study the ...

Nanosecond gated optical sensors for ocean optic applications

Proceedings of the 2006 IEEE Sensors Applications Symposium, 2006., 2006
Nanosecond gated photosensitive modules with wide dynamic range has been design for ocean optic applications (1) on base R7400U Hamamatsu (5mm. active area) photomultiplier tube. The photomultiplier tubes R7400U series have two kinds of photocathode: low resistance semitransparent multialkali photocathodes that can be gated with nanosecond response and

Raman scattering and in-water ocean optical properties

Applied Optics, 1990
Inelastic (transpectral) scattering may contribute significantly to the in-waterlightfield. Major mechanisms for inelastic scattering include Raman scattering, which we show is important in clear ocean waters, and fluorescence from a variety of sources, which may be important in more turbid waters.

Isotropic spherical source analysis for ocean optics

Applied Optics, 2000
Plane-to-point transformations are used to develop a version of the Hydrolight computer program with which to compute the spatial dependence of the irradiance and the scalar irradiance of the light field away from an isotropic point source deep within a spatially uniform ocean.
